By default, micro-isolation CAR is enabled for OSPF, implementing micro-isolation protection for OSPF packets based on interfaces and destination IP addresses to protect session establishment. When OSPF packets encounter a traffic burst, a large number of packets of non-OSPF neighbors may preempt interface bandwidth resources. In the case of an attack, a large number of invalid packets sent to other IP addresses may preempt the bandwidth. Therefore, you are advised not to disable this function.
The system view is displayed.
Micro-isolation CAR parameters are configured for OSPF.
In normal cases, you are advised to use the default values of these parameters. pir-value must be greater than or equal to cir-value, and pbs-value must be greater than or equal to cbs-value.
Micro-isolation CAR is disabled for OSPF.
By default, micro-isolation CAR for OSPF is enabled. To disable this function, run the micro-isolation protocol-car ospf disable command. If this function is disabled, micro-isolation protection is no longer implemented for OSPF packets based on interfaces and destination IP addresses. In normal cases, you are advised to keep micro-isolation CAR enabled for OSPF.
The configuration is committed.
